I’m exclusively using Arch without any issues. I pretty much used my GPD Pocket 2 guide for the install.
Things to note (that differ with the guide):
- rotation on the P2Max is normal, so no need to use the kernel option (
fbcon=rotate:1
) or Xorg30-display.conf
(mentioned in the guide) - for the touchscreen to work, you’ll need this DSDT override cpio image loaded before any other initrd images
- you’ll probably want to make some changes to your trackpad config to improve scroll speed
